Reporting method, detection method, device and system for network state

摘要

A reporting method for a network state includes: an intermediate node receiving a data packet; the intermediate node marking the data packet according to the current network state; and the intermediate node forwarding the marked data packet. A detecting method for a network state includes: a sink node receiving a data packet; the sink node parsing the data packet to obtain the marking information about the network state; and the sink node determining the network state according to the marking information. A reporting device corresponding to the reporting method, a detecting device corresponding to the detecting method, and a detecting system comprising the reporting device and the detecting method are also provided.

1. A reporting method for a network state, comprising:
an intermediate node receiving a data packet; said intermediate node marking said data packet according to a current network state; said intermediate node forwarding the marked data packet; wherein, said data packet carries a source node identity and a data packet sequence number; said intermediate node marking said data packet according to the current network state comprises: said intermediate node judging whether said data packet is a first data packet sent by said source node or not according to said source node identity, if yes, checking whether said data packet carries identity information of other nodes or not; if it is checked out that said data packet does not carry identity information of other nodes, said intermediate node writing an intermediate node identity into a specified subfield in said data packet, and recording said source node identity and said data packet sequence number in a local data structure.
